George L. White enlisted in the Union Army at the age of 31. He mustered into service on August 21, 1861, joining the 7th Maine Infantry Regiment, Company A out of Houlton, Maine. He was discharged in 1863 after an absence due to an unknown cause. According to Claude Charette's "Civil War Men From Fort Kent in Union Forces, 1861-1865" (MCC-00237), White was from Fort Kent and was married. However, the 1850 U.S. census for Aroostook County has a George L. White listed as a resident of Hodgdon, in southern Aroostook County, age 19 and working as a farmer. He is again listed as a resident of Hodgson in the 1880 census. It has not been determined whether the two listings are of the same person.
